List<? super Integer> foo3

Reading - Given the above possible assignments, what type of object are you guaranteed to receive when you read from List foo3:

  • You aren't guaranteed an Integer because foo3 could be pointing at a List<Number> or List<Object>.
  • You aren't guaranteed an Number because foo3 could be pointing at a List<Object>.
  • The only guarantee is that you will get an instance of an Object or subclass of Object (but you don't know what subclass).
